Abstract: TOOL PRESETTING FIXTURE               ABSTRACT OF THE DISCLOSURE         A tool presetting fixture is disclosed for use with cross-slide type tool holders which are usable on a multiple spindle automatic machine tool.  The tool holder has a tool holding pocket to hold a cross-slide type tool with a tool tip. The fixture has a base with a first gage surface mounted for movement parallel to the base to gage the spindle centerline height of a tool tip in the tool holding pocket. The fixture also has a rear wall on the base which has a second gage surface perpendicular to the base.  Gage means is provided to gage the distance from this second gage surface to the tool tip and screws arc provided in the tool holder and acting on this second gage surface to obtain a gaged dis-tance of the tool tip from a reference surface of the machine tool to establish a predetermined longitudinal dimension on the workpiece.  Further a side wall on the fixture provides a third gage surface perpendicular to the base and also perpen-dicular to the second gage surface and this permits gaging the distance of the tool tip to this third gage surface to gage the workpiece cutting radius.  The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: Abstract The invention relates to a process for separation of methacrylic acid from a methacrylic acid-containing, gaseous reaction mixture obtained by subjecting methacro-lein, or a compound which can afford methacrolein under the reaction conditions, and molecular oxygen to gas phase reaction in the presence of a catalyst for oxidation in the presence of an inert gas for dilution.  The process comprises (a) cooling the gaseous reaction mixture from a reactor wherein the gas phase reaction has been effected to separate it into condensable components including meth-acrylic acid, acetic acid and water vapor as a condensed liquor and non-condensable components including methacro-lein as a non-condensed gaseous mixture, (b) eliminating contaminating methacrolein from the condensed liquor, and (c) contacting the resulting condensed liquor with an organic solvent to extract methacrylic acid, followed by separation into an organic solvent solution including methacrylic acid and an aqueous solution as waste water. The important features are that (1) the inert gas for di-lution is a non-condensable gas or its mixture with water vapor and (2) the aqueous solution ultimately separated is evaporated and the evolved vapor is subjected to catalytic combustion with molecular oxygen.  As a result of this process the amount of waste water to be discharged is much suppressed, which reduces pollution problems or the cost of treating the waste water to eliminate pollutants.

Abstract: Abstract of the Disclosure A new silicon based semiconductor device comprises a layer of amorphous silicon in which the density of energy states in the energy gap has been reduced by hydrogenation; this layer is associated with a layer of a hydrogen-containing substrate material that can supply hydrogen in atomic form to the amorphous silicon.  In processes of the invention the silicon layer and a substrate layer are hydrogenated separately to permit optimum hydrogenation; the silicon layer may be deposited without hydrogenation and hydrogenated subsequently with hydrogen from the substrate material.  A specific example consists of a layer of hydrogenated amorphous silicon of about 1 micrometer thickness deposited on a hydrogen-containing chromium layer which is itself deposited on a carrier, the silicon then forming the active element of a photovoltaic cell particularly functional as a solar cell.

Filed: 1981-06-17
Granted: 1983-02-22
Abstract: Abstract:          CONTINUOUS PROCESS FOR THE MANUFACTURE OF CYANURIC ACID      A highly-pure cyanuric acid is manufactured in a continuous process whereby urea and/or biuret are dissolved in an inert solvent and circulated at a high velocity and a temperature in the range of about 180°C to about 250°C through a loop between a heat exchanger and a forced circulation evaporative crystallizer body. Cyanuric acid crystallizes from the reaction mixture as it circulates to form a slurry.  Ammonia formed during the reaction is removed at reduced pressure as the reaction mixture enters the evaporative crystal-lizer body.  A portion of the slurry of cyanuric acid is continuously removed as it circulates through the loop and may be filtered to recover the cyanuric acid. The filtrate is returned to a feed tank and additional solvent, urea or biuret added to meet the concentration desired in the reaction mixture.  The solution from the feed tank is added to the reaction mixture circulat-ing through the loop at a rate to replace the volume of cyanuric acid slurry that is removed.

Abstract: Bituminous Finisher Abstract of the Disclosure The invention relates to a travelling finisher apparatus for laying down a road surfacing layer of a bituminous compound material, comprising a first precompacting and levelling plank carried by a plank frame, and optionally a second levelling plank connected to a vibratory drive arrangement, whereby a particularly high degree of compact ion is achieved so that subsequent roller compaction is not required. This is accomplished by providing a vertic-ally guided compactor bar extending transversely of the direction of travel at the rear of the first levelling plank in the direction of travel and being of substant-ially narrower width than said first levelling plank, said compactor bar being continually in contact with the surface of the precompacted surfacing layer and adapted to be acted on by linear pulsating forces acting between the plank frame and the compactor bar, and generated by a drive source the reaction forces of which are absorbed by the plank frame. As the reaction forces are taken up by the plank frame, it is possible to make use of the mass inertia of the plank frame and the components asso-ciated therewith for generating extraordinarily high force levels at the compactor bar.  Together with the narrow contact surface of the compactor bar, this results in very high area unit loads enabling the required high compaction degrees to be achieved.            This is also enhanced by tuning the frequency of the compaction force pulses to the natural frequency of the system. The compactor bar and the levelling plank fol-lowing it may be divided into sections adapted to be angularly adjusted relative to one another for forming roof- or trough-shaped surface profiles.

Abstract: ABSTRACT OF THE DISCLOSURE      Blood Fractionation Improvement The extraction of Factor VIII, the antihaemophilic factor in blood, is difficult due to its instability and the presence of impurities.  An initial Factor VIII containing aqueous solution such as blood plasma is purified by subjecting a Factor VIII containing aqueous migrant solution to continuous flow electrophoresis wherein flow takes place in an annular separation chamber and is stabilised by means of an angular velocity gradient; and collecting a separated Factor VIII component.      In order to separate the Factor VIII from albumin and firbrinogen, whilst obtaining good recoveries of Factor VIII (e.g. ?60%), the migrant solution is prepared by precipitating Factor VIII from the initial solution using an organic liquid such as ethanol, and removing and redissolving the precipitate in an aqueous medium and adjusting the pH to be within the range of 7.5 to 8.6, preferably 8.3 to 8.6.
